Company History

Our business was started by Dennis and Flo Jaenke in 1969. Dennis was an auto mechanic by day and worked on furnaces and air conditioners in the evenings. His father has worked at a sheet metal shop and taught Dennis about the business, and got him interested in it. After a lot of discussion, Dennis and Flo decided to start their own HVAC business, and they purchased a vacant building and converted into the shop they still use today (it is located at 423 S. Library in Waterloo, IL). In the beginning, Dennis went on all of the service calls and Flo handled the bookkeeping and answered the phone. When work started coming in, they were able to hire an employee and continue to expand the business. There are currently 4 employees.

In 2006, Dennis passed away and Darren, Flo's son-in-law, has stepped up to help run the business. He is Flo's right hand man, and does all of the estimating and selling of jobs. He also helps with installation and services as needed. Mike is our main serviceman. He also helps with installation if service is slow. Pat handles installation and ductwork. Our group of guys is versatile and are willing to do whatever it takes to get the job done. Our team members attend regular seminars to keep them in tune with the latest HVAC technology and products.
